EYEGLASSES.

Division in part of application Serial No. 689,663, filed February 29, 1912. This application filed October 18, 1915. Serial No. 56,645.

To all whom it may concern:

Be itknown that we. JOEL C. Villas and I'IAHRY H. S'I'YLL, citizens of the United States, residing at Southbridge, in the county of \Vorcester and State of Massachusetts, have invented certain new and use ful Improvements in Eyeglasses, of which the following is a specification.

()ur invention relates to improvements in eyeglasses and has particular reference to that form of eyeglass in which the guards are carried by spring actuated levers.

One of the leading objects of the present invention is the provision of novel and improved means for securing the spring and lever in position on the mounting.

A further object of the invention is the provision of an improved mounting in which the guard and spring may be readily removed and replaced without the employment of screw drivers or other tools.

A still further object of the invention is the provision of a mounting of this character in which the spring will serve to lock the various parts in position on the mounting, and in which the lever will be held between rigid bearings, preventing weaving or tilting ,movement thereof.

Other objects and advantages of our improved eyeglass mounting should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, forming a part thereof, and it is to be understood that we may make any modifications in the specific details of construction shown and described within the scope of the appended claims.

without departing from or exceeding the spirit of our invention.

Figure I represents a front perspective view of a mounting embodying our invention. Fig. II represents an enlarged perspective view of the parts in disassembled relation. Fig. III represents a top plan view of the structure illustrated in Fig. II. Fig. IV represents a sectional view on the line IV-IV of Fig. III. Fig. V represents a view similar to Fig. IV but illustrating a sli htly modified construction, and'Fig. VI rep esents a sectional View on the line VIVI of Fig. V.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the lenses of the mounting connected by the lens attachment 2 and bridge member 3, said bridge member being formed at each end adjacent the'lens attachment with the seat 4 for the guard arms or fingerpiece levers 5, which carry. the gnard 6 for retaining the mountmg in position on the face of the wearer.

In that form of our invention illustrated in Figs. II to IV inclusive,we have shown secured in the seat 4 as by soldering, or riveting, the main or attaching post of the mounting. This member has the" portion 7 fitting within the seat 4 and immediately thereabove the bearing portion 8 on which the lever turns. Rising above this hearing portion' is the slotted tube or barrel 9 having a slot 10 at each side andhaving the diametrically opposite lip-11 partially over-hanging the slot, as is best illustrated in Fig. II. In assembling this type of mounting we first place the guard lever 5 resting on the seat 4 with its aperture encircling the bearing portion 8 and then preferably slide over the sleeve 9 our improved locking member.

consisting of the slotted sleeve or tube 12 having the basal flange 13 adapted to rest on the shoulder at the top of the bearing portion 8' and to project outwardly over the lever, as illustrated in Fig. IV. With the parts in this position and the slot 14' of the member 12 alined with the slot 10 ofthe post,

the inwardly bent end 1'5 of the fiat spiral spr ng 16 is then slid downward in the slot to its lowermost position, when the lower edge of the coils of the spring will be found to rest on the flange 13. The spring is then slightly tensed and hooked onto the lard arm, this tensing of the: spring slightly winding the same and causing the inner end 15 of the spring to slightly rotate and become looked under the lip 11, as will be best understood by reference to Fig. III. With the spring in the position shown in Fig. III it will be understood that it will be impossible for the portion 15 to move upward on account of the engagement of the lip 11 with the upper edge of the spring end 15, while at the same time the engagement of the lower edge of the portion 15 with the flange 13 at the termination of the slot 14in the locking member 12 securely retains the locking member and thus insures rigid or fixed bearings, preventing any tilting movement of the lever. Y

To remove the guard it is merely necessary to disengage the spring from the guard, when: slight unwinding movement of the spring will shift the portion 15 out from under the lip 11 and permit the locking member and spring to be readily slipped off the upper portion 9 of the fixed post, when the guard may be readily removed or the spring changed or adjusted, as desired.

In Figs. V and VI, we have illustrated a slight modification of our invention. In these forms the central member or post 9 has the under-cut slot forming the lip 11 as before, but in place of the spring shifting to engage under the lip, the locking member 12 is provided with inwardly bent tongues or flanges 17, as best illustrated in Fig. VI. In the use of this form of the invention the locking member is placed in position and slightly rotated to bring the portion 17 beneath the lip 11 and the spring 16 is then merely slipped down over the locking memher. the locking member being provided with a slightly upset portion or bead 18 around the upper edge thereof engaging with the inner coil of the spring to retain it against upward movement, while the presence of the inner end 15 in the slots of the post and locking member securely retain the inturned flanges 17 beneath the lip 11 and prevent disengagement of the locking member from the post without removal of the spring. In this form of our invention the spring in place of itself being the lock to prevent upward movement of the parts, serves, so far as its inner end 15 is concerned, merely as a wedge-or block to hold the parts in locked relation, while at the same time in either form of our invention the slot in the fixed-post serves to retain the inner end of the'spring against rotation relative to the remainder of the mounting.

Attention is also invited to a further slight modification illustrated in Fig. V, in that the post in place of being secured to the bridge by riveting or soldering is separate therefrom and is held locked in engagement therewith by means of the screw 19.

"Ve claim:

1. An eyeglass mounting comprisingv 9.

nose bridge having a tubular stud having a slot one wall of which has a projection, a nose clip member pivotally mounted on said stud, a' sleeve mounted on said stud and hav ing a slot adapted to register with the slot of said stud, and a spring having an end eX- tending through both of said slots, said spring being under tension whereby said sleeve is rotated to bring its slot into registry with said projection of the stud, substantially as described.

2. An eyeglass mounting comprising a nose bridge, a stud thereon having a slot provided at one edge with a spring engaging projection, a nose clip member pivotally mounted on said stud, a slotted thimble embracing said stud and having a continuous wallv adapted to bear against said nose clip member, and a coil spring embracing said thimble and having one end extending through the slot in said thimble and into said stud slot and the other end engaged with said nose clip member whereby the tension of said spring acts to hold the thimble with its slot in registry with said spring engaging projection.

3. An eyeglass mounting comprising a nose bridge having an integral stud having a pair of slots one of which has a laterally extending projection, a nose clip member pivotally mounted on said stud, a slotted thimble mounted on said stud and having a flange adapted to bear against said nose clip member, a coil spring embracing a part of said thimble and having an inner end portion extending through said slot of said thimble and through the stud slot having said projection, the extreme inner end of said spring seated in said secondslot of said stud and the outer end of said spring se- 'cured to said nose clip member, substan tially as described.

' In testimony whereof we afiix our sigmtures in the presence of two witnesses.
